Buzz...your clutch ain't cable activated....trust me on this! You're really a rooky at this, aren't you?
No prob...we were ALL rookies once.
Almost any mechanical fuel pump will work, provided it's for an FE block. With a moderate cam and dual 4's, I'd be sure I'd and tell Summit what you're runnin'...and Yes, you can get too much pressure. Your SPF dealer - either Dynamic in Ohio, Reed Motorsports in New Orleans, or Olthoff Racing in Charlotte should be able to steer you in the right direction. Have you asked them...?
Your fluid leak could be coming from a several locations....but the most likely ones are your clutch slave cylinder, your clutch reservoir, or even your transmission. You'll need to get under the car to tell...lift, hoist, or even a floor jack and jack stands will do the trick. But, please don't climb under the car without supporting it on jack stands!
If it's your clutch slave cylinder...it'll be leaking from the black rubber boot on the slave cyclinder located on the driver's side of the bell housing. If this is the case...there's two possible fixes.
One is your clutch push rod is too long
and just needs to be adjusted. This changes your release point on your clutch, so be mindful of that. What happens is it's not allowing the clutch fork to fully release and the residual pressure is forcing fluid past the seal. Simply shorten the rod a little through the adjustment nut and then check out your clutch travel and release point.
The other possibility is that your slave cylinder needs rebuilding...but it's most likely a misadjusted clutch.
If it's your clutch reservoir, it'll most likely be the black rubber hose running from the reservoir to the clutch master cylinder...it's a known problem. The hose just needs to be replaced. But, again...check with one of the SPF dealers for the right hose. It's NOT just a length of black rubber hose...trust me on this! The wrong hose can complicate your problem, and cause other related issues as well.
If it's your tranny...it'll most likely be leaking from the speedo cable fitting. There's a little trick to sealing this up. You'll need to remove the speedo cable from the tranny by unscrewing the silver threaded cap. Then using an alcohol soaked rag, wipe the cable off around the collar and a couple of inches up the cable. Make sure it's
oil free and as clean as you can get it. Then, using some clear silicone sealer, smear a thin coating around the cable where the plastic cable housing goes in to the silve ferrule of the fitting. This will seal this part of the cable which is usually where it's leaking. Then, screw the collar back on the speedo fitting and re-tighten. Also...make sure there's a O-ring in the fitting...if not, you'll need to replace it as this is another source of leaks.
If it's not coming from one of these locations, I'd be surprised....but, let us know. There's other locations, too, but these are the most likely on an SPF.
Hope this helps... SCOF is a big help, too, and don't discount it. There's a lot of knowledgable SPF owners over there and they can help a lot. There's also a lot of others over there, too...but...well, hell, you'll see.
But they're a good source of help...especially for new SPF owners...and lots of fun, too!
Keep in touch...and let us know what pans out.
